Holden Cruze Code 79 [Meaning & How to Reset]

In this article, I am going to explain what code 79 means on your Holden Cruze, and how to reset it. without wasting any more time let’s get to it.

Holden Cruze Code 79 Meaning

In short, the code 79 coming on your Holden Cruze dash is a maintenance alert indicating that you need to change the oil and oil filter.

Fresh clean engine oil is crucial for the proper lubrication of your Holden Cruze engine, and the filter helps remove dirt particles from the oil before they can reach your engine’s moving parts and cause damage.

Importance of Oil and Oil Filter Change on a Holden Cruze

Now, that you know what code 79 means on your Holden Cruze, I wanted to touch on why this is critical for the performance and longevity of your vehicle.

As a mechanic, I often see people that don’t change their oil and filters as often as they should, or worse yet, never at all. This can lead to premature wear of engine components and even catastrophic failure.

1. Engine Oil

Engine oil is what keeps the moving parts of your Holden Cruze lubricated so they can move smoothly without friction.

This helps reduce wear and tear on your engine over time, which can save you money in repairs down the road.

Oil also helps prevent corrosion by providing a barrier between metal surfaces in contact with each other.

The Engine oil is also responsible for cooling some engine components on your Holden Cruze Cruze by carrying away heat from the engine.

This helps prevent premature wear in your Holden Cruze engine and keeps it running at a consistent temperature.

2. Oil Filter

The Oil filter goes hand in hand with the engine oil. An oil Filter is responsible for removing contaminants from the engine oil, which can help prevent premature wear.

A dirty oil filter will not only limit the number of contaminants that can be removed, but it also slows down the flow of oil through your Holden Cruze engine.

It is important to remember that every time you change the motor oil in your Holden Cruze, it is also important to change the oil filter as well.

This will ensure that you are not only using a fresh supply of clean motor oil but are also removing any contaminants that may have been trapped in your existing filter.

Now that we’ve gone over what code 79 means, let’s talk about how to fix and reset it so the check engine light goes away from your Holden’s dash.

In order to reset the code you will need to change the oil and oil filter before it can go away.

There are three ways to go about doing that, you can either take your Holden Cruze to Dealer, or independent mechanic, or Do it Yourself (DIY).

You can simply take your car to a dealership or independent mechanic and have them reset the code for you.

Fortunately, from personal experience, it is relatively easy to change the oil and filter on your Holden Cruze

DIY Approach

If you are going to it yourself, here is an overview of what needs to be done

  1. Gather tools and materials.
  2. Under the car, locate the oil drain plug (a large hexagonal-shaped nut that is screwed into a threaded hole).
  3. Remove it with a wrench or, on some vehicles, by hand.
  4. Allow old oil to drain from the engine onto a bucket or other absorbent material
  5. Once drained replace the filter assembly back onto the engine block
  6. Remove the old oil filter, and then install the new one.
  7. Fill with oil until it reaches your vehicle’s fill line. Check that you have enough oil in your engine by checking its dipstick level

The recommended oil change interval is every 4000 -5000 Km (3000 miles) or 6-12 months, whichever comes first. At every oil change, you should also replace the oil filter and check for leaks.
